The San Diego Union Tribune has an outstanding summary of the recently-unveiled SpaceShipTwo (SS2) (Wikipedia), successor to SpaceShipOne, which became the first private vehicle to reach space in 2004 and won the $10m Ansari X-Prize. SS2 is vying to become the world’s first commercially operational spaceplane and the first in Virgin Galactic’s fleet. Pictured at left is Virgin founder and multi-billionaire Richard Branson, and to his right, Burt Rutan, designer of SS1 and SS2. The PDF does an excellent job of illustrating the basics of an SS2 flight, though at nearly 9mb, the file isn’t a quick download.
At a press conference this morning at the National Press club in Washington, the Space Solar Alliance for Future Energy (SSAFE) announced a milestone demonstration of the critical technology enabling SBSP: long-distance, solar-powered wireless power transmission. The demonstration project, led by NASA veteran John C. Mankins, demonstrated microwave power transmission between two Hawaiian islands 148 kilometers apart, more than the distance from the surface of Earth to the boundary of space. Although SBSP satellites would ultimately operate at much higher altitudes in the geosynchronous orbit (35,786 km AMSL), Mankins has successfully demonstrated the feasibility of long-distance energy transmission in principle.
Those of you who haven’t “cut the cord” to television (as I did about 5-6 years ago) may be interested to watch a special episode of Discovery Project Earth entitled “Orbital Powerplant) that will debut tonight at 10 pm with reruns on September 13 at 2am and noon.
This video provides more background on SBSP (until recently known as “Space Solar Power”):
